%X 探讨毛细透排水带的毛细力，开展室内砂土排水试验，分析砂土中设置毛细透排水带下的流速、含水量以及其防淤堵性能。研究结果表明，路基、边坡等构筑物上毛细透排水带铺设的角度取值范围建议为10°~15°，毛细透排水带加强了砂土的排水能力，在变水头非饱和阶段埋深对排水效果影响微弱，毛细透排水带能够促使其周边土体形成反滤层。该研究成果为毛细透排水带的实际工程应用提供了参考。<br>In this paper, the capillary force of the drainage belt was discussed, and the laboratory experiment of sand drainage was carried out. The flow velocity, soil moisture and the anti-clogging performance in the condition of setting capillary drainage belt in sand were than analyzed. The results show that the range of suggested angle for capillary drainage belt is from 10° to 15° for slopes and other structures, and the belt strengthens the drainage capacity of the sand. What’s more, buried depth only has a little influence on drainage effect in unsaturated period under variable water head, and the inverted filter could be formed under the influence of capillary drain belt. The research results provide practical value for the engineering application of capillary drainage belt
